HAIR-PIN.

SPECIFICATION forming part of Letters Patent No. 452,055, dated May 12, 1891.

Application filed January 31, 1890. Serial No. 338,735. (No model.)

To all whom it may concern.-

Be it known thatI,WILLIAMF.YOUNG,a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have i11- vented certain new and useful Improvements in Hair-Pins; and Ido hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

My invention relates to hair-pins and has for its object to construct a hair-pin having barbs along the length of the same for the purpose of retaining the pin permanently in position when in use, to prevent the disarrangementof the hair.

A further object is to render it possible to barb the wire prior to being bent into the required shape, thereby cheapening the product and rendering the same uniform.

The invention will first be described in connection with the accompanying drawings, and then pointed out in the claims.

In the drawings, Figure 1 is a perspective ofa hair-pin made in accordance with my invention, showing the same provided with four rows of barbs. Fig. 2 is a detail view in side elevation of a piece of wire, showing the same provided with two rows of barbs. Fig. 3 is a sectional view taken on the linex acof Fig. 1, showing more clearly the arrangement of the barbs. Fig. 4 is a section taken on the line y y of Fig. 2. Fig. 5 is a perspective view of the part'shown in Fig. 2 on an enlarged scale.

In order to be enabled to produce the finished article at a minimum expense it must be man ufactured mechanically-that is,the barbs must be formed by passing the wire through barbing-rollers, which barbs do not by preference extend beyond the surface of the wire. This operation will of necessity produce a wire having a series of barbs of a like inclination throughout the entire length of the wire, as shown in Fig 2, which when out to the desired length and bent in proper shape will produce a pin having one prong in which the inclination of the barbs are from the point to the bend, while on the opposite prong the inclination of the barbs will be from the bend to the point, thereby forming but one prong with the barbs inclined in a direction to engage with the hair. While this construction is far superior to that in which the pin is formed of plain wire, I prefer to form the wire with the barbs in opposite inclination, as shown in Fig. 1, in which there are four rows of barbs disposed longitudinally of the same with a smooth or unbarbed portion A between each two rows, two of the rows incliningin one direction and the remaining two rows inclining in an opposite direction whereby when the pin is formed there are two rows of holding-barbs along the entire length of both prongs-that is to say, with the inclination of the barbs from the point toward the bend. This construction allows of formingthe entire pin by means of machinery, thereby reducing the expense to a minimum and producing a p perfect product.

In the drawings, A designates the wire formed with barbs B, after which the wire is cut into the desired lengths and bent at O to form the hair-pin D.

It will be seen from the above that I have produced a pin possessing great advantages over those now in use, and at a costof manufacture not to exceed that of the ordinary make.

What I claim is 1. A hair-pin formed of a piece of wire having a plurality of rows of barbs wholly within the contour of the wire and separated from each other by unbarbed portions.

2. A hair-pin formed of a piece of wire having a plurality of rows of barbs wholly within the contour of the wire and separated from each other by unbarbed portions, the barbs in one series of rows being inclined in a direction opposite thosein another series of rows.

In testimony that I claim the foregoing as my own I hereby affix my signature in presence of two witnesses.
